I was at a conference in Chicago and I met a mutual acquaintance of a friend of mine who had moved away. I hadn't thought about her in months, but running into someone that I knew she knew made me think of her and I decided to write her a postcard. As it turned out, when I checked my messages at home, she had called me that same day.
I ran into the ex boyfriend of one of my good friends. They were two young and it just didn't work out at the time, but they've both been fond of each other. He told me to say hi to her and when I told her she remarked that for some reason she had just been thinking about him recently.
